Hospital logistics and supply chain management are increasingly supported by service robots such as TUG units. These robots transport supplies, medications, meals, and lab samples autonomously. Their ability to navigate hallways and elevators without staff intervention saves time for nurses and technicians. This ensures deliveries remain on schedule and reduces manual handling errors.

Patient care and elderly assistance

Patient care and elderly assistance are becoming more effective with therapeutic and companion robots. PARO provides comfort and social interaction for dementia patients, while service robots remind patients about medication, check vital signs, and alert caregivers when needed. This is particularly valuable in regions with aging populations where healthcare staff are stretched thin.

Rehabilitation and therapy

Rehabilitation and therapy programs now use robots to help patients regain movement and independence. Exoskeletons such as Cyberdyne HAL enable stroke and spinal cord injury patients to practice walking with real-time feedback. 

Robotic therapy arms provide consistent, measurable exercises that adjust as patients recover. These systems extend the reach of therapists while delivering personalized, data-driven care.
